Regulation is essentially a necessary evil for mainstream adoption/acceptance whether people like it or not. What is problematic is the level of regulation it receives. Minimal is fine and perfectly acceptable but if they start making complex regulations around it then it will become troublesome to use and work out your taxes on it.
Technically it is not possible to regulate, and in fact banks are dodging government regulations regularly using different tricks. So I don't think bitcoin business will be any different, they will always find a way to get around regulation, because the governments are technically incompetent to regulate either banks or bitcoin
They won't regulate bitcoin directly but just people using it. They'll tax the products purchased with it in the same way fiat is taxed on regular goods and services etc. People evading taxes and laws will be punished in the usual way.
Bitcoin cant be regulated. Any attempt to control it would render it invaluable.
How do you work that out? Please expand and clarify your statement.
